How to Invent a Product

1.

It's unnecessary to think of something that no one has ever thought of before. Just ask yourself what exactly you are trying to improve or solve? If you want to build a better dust mop (拖把),how will it be better? What interesting or important part does it have? What could you do differently?

2.

Try coming up with 15 solutions in a minute, no matter how crazy. Or choose one of the solutions and ask how is that like my idea? "How and why does it work?" "When, where and how is it used?" "How is it described?" Let your questions and imagination come up with new ideas or find a different way of looking at a problem

3.

Visit stores that offer products similar to what yours will do and even go as far as to ask store workers for products they might sell with a similar purpose. If you have a name for your product created, search this to find out whether it is already being used.

4.

This is often the longest part of inventing! Thomas Edison's lab tested more than 6,000 different materials for light bulbs before they came up with one that worked. Make the model until it works the way you want. Sometimes you might discover an entirely different idea.

5.

When you think you've got everything ready, it's time to make a working model of your invention --- a prototype. This is what you'll use to show people what it will look like and how it will work. You can use this prototype to show and introduce to the people who might have interest.

A.Research your invention.

B.Brainstorm

C.Ask for advice.

D.Find a problem worth solving.

E.Make your invention to a reality.

F.Build, test, rebuild, repeat.

The biggest secret about inventing is that anybody can do it! Perhaps this sounds crazy, but it's true. Maybe you have the wrong idea about inventing, so read on to discover the truth.

★Wrong idea No. 1: An invention has to be something completely new.

Inventing means creating something "new", but the idea could come from something that already exists(存在). The Wright Brothers, for example, got the idea for building a "flying machine" from watching birds.

★Wrong idea No. 2: Inventors are born, not made.

There are a lot of factors(因素)that make invention possible. Take Mozart for an example. He was born with a (3)talent for musical composition. But other factors were also important for his creativity. His father was a music teacher, and Mozart practiced for hours every day, from the time he was four years old. Thomas Edison said that being an inventor was "99% hard work and 1% inspiration"!

Very successful creators don't give up when they get something wrong. As one inventor said, "A failure was the right answer to the wrong question."

★Wrong idea No. 3: Inventors are always old people.

Don't believe that you can't invent something when you are young. Here are two examples of young inventors：Louis Braille went blind when he was a child. When he was fifteen, he invented a system of reading and writing for blind people that is still used in most countries today.

As a young man, George Nissen was watching some artists performing in a show. He watched how they fell into the safety net and then jumped back up again. This gave him an idea, and he invented the trampoline(蹦床).

1.It's a friendly way people in the United States greet each other. But "How are you?" is also a very unusual question. It's a question that often doesn't have an answer.

When a person meets a friend on the street and asks "How are you?", the person doesn't really expect to hear an answer such as "I really don't know what's wrong with me.I thought I had a cold.I look some medicine, but that didn't help much, so I'll go to the doctor." The person who asks"How are you'" expects to hear the answer "Fine." even if the other person isn't! The reason is that "How are you?" isn't really a question and "Fine" isn't really an answer. 2.

Sometimes, people also don't say exactly what they mean. For example, when someone asks "Do you agree?", the other person might be thinking "No, I disagree. I think you're wrong." But it isn't very polite to disagree so strongly, so the other person might say, "I'm not so sure." 3.

People also don't say exactly what they are thinking when they finish conversations with other people. For example, many conversations over the phone end when one person says, "I've got to go now." Often, the person who wants to hang up gives an excuse： "Someone's at the door." I've got to put the vegetables away." "Something is burning on the stove!" 4.Perhaps the person who wants to hang up simply doesn't want to talk any more, but it isn't very polite to say that. The excuse is more polite, and it doesn't hurt the other person's feelings.

Whether they are greeting each other, talking about an opinion, or ending a conversation, people often don't say exactly what they are thinking. It's an important way that people try to be nice to each other.5.

A.We must learn when to keep silent.

B."How are you?" is a nice question.

C.And it's all part of the game of language!

D.The excuse might be real, or it might not be.

E.It's a nicer way to say that you don't agree with someone.

F.People sometimes shake hands when they meet each other.

G.They are simply ways of greeting people and saying "Hello."

Alexis Lewis is a teenager from the USA. She likes to invent—to think of new ideas for things that no one has made before, and then make them.

Alexis often enters competitions for young inventors. When she was younger she spent time with her grandfather, who made transport for people to go to space. One day Alexis’ mother told her about a newspaper article which explained how difficult it was to get sick people through the countryside to hospital in Africa. Alexis wanted to help.

Alexis knew that in North America, before there were cars, horses pulled heavy things on a travois(旧式雪橇) made of wood. Alexis thought people could do the same, but she added wheels. To make her travois light, she used bamboo, a plant which grows in Africa, not wood.

To pull Alexis' travois, you wear a belt, which means you can carry or hold other things. Alexis thinks her travois might be useful for carrying food home from the market, as well as taking people to hospital. Now it's finished, she's writing instructions for building one so people in Africa can make it themselves.

With help from US companies, Alexis plans to give ten travois free to hospitals in Africa. She doesn't want money for them because they are for poor people.

Alexis doesn't know if she wants to be an inventor when she's older, because she also likes music and writing, but she thinks it's important for children to learn about inventing at school.

1.Why did Alexis decide to invent a new type of transport?

A.Because she wanted to win a competition.

B.Because her mother told her about a problem.

C.Because her grandfather worked on spaceships.

2.How is Alexis' travois different from those pulled by horses?

A.It's heavier. B.It is made of wood, C.It has wheels.

3.What does the author say about using Alexis' travois ?

A.People will need instructions to use it.

B.People should not use it to carry shopping,

C.People can pull it by wearing a belt.

4.What does underlined word "them" in the fifth paragraph refer to?

A.US companies. B.Ten travois. C.Poor people.

5.Why does the author write the passage?

A.To ask for help with a problem.

B.To advertise a new way to travel.

C.To tell the story of someone's idea.

How can you change negative ( 极其负面的) thoughts? Many people suggest thinking of something bright and happy. However, scientists from Queen’s University in Canada said that there might be another way: by walking like a happy person.

“It is not surprising that our feeling affects how we walk, but we want to see whether the way we move also affects how we feel,” explained Nikolaus Troje, the lead scientist, to The Independent.

Scientists believe that the way we remember emotional ( 情绪的) messages is affected by our mood. Those who feel sad remember negative information far more easily than positive messages, especially when the information is about them.

In order to prove（证明）this, Troje and his team watched 47 people walking on the treadmill (跑步机) by cameras. Half of the people were encouraged to follow a depressive walking style, while the other half moved like a happy person. Walking speed was kept the same for both groups.

Meanwhile, the scientists read out a list of positive and negative words, asking people to decide whether or not each word described them well. Afterwards, people were asked to recall as many words as they could remember.

As expected, those who followed a depressed walk recalled more negative words than those that walk in a happy manner.

This shows that our walk influences the way we deal with information. And the scientists believe that using a happy walking style could help with treatment for depression.

1.Scientists from Queen’s University think that we can change negative thoughts by 　　 .

A.remembering emotional messages B.thinking about a happy person

C.walking like a happy person D.hanging out with friends

2.What does the underlined word “depressive” mean in Paragraph 4?

A.快乐的 B.快速的 C.慢的 D.抑郁的

3.What do we know about Troje’s test?

A.Scientists took photos of the walking styles of 47 people.

B.47 people recalled all the words after walking.

C.47 people were asked to walk at different speeds.

D.Those who walked like a happy man recalled more positive words than those that followed a depressed walk.

4.According to the story, the scientists’ findings can help 　　 .

A.treat depressed patients B.improve one’s acting skills

C.deal with memory loss D.encourage people to exercise
